Miley Cyrus Super Fan Explains Viral Prom Video

He's the high school student whose video invitation to Miley Cyrus to the prom went viral and we tracked him down to get the latest on his proposal and to test his knowledge of Miley trivia!

In the YouTube video posted by 17-year-old Matt Peterson -- now approaching 300,000 hits -- he poses his invitation a couple of different ways. In the final one, he faces the camera naked, covering his private parts with the same kind of foam finger Miley famously wagged during her VMA performance last year.

ET sat down with the high school junior Thursday at his home in Phoenix, where he explained that he first met Miley during a radio station appearance in 2009 and that she also gave him a shout-out during a concert performance. "I'm blown away by the response," Matt said. "The first day I posted it
every kid from my school was tweeting it, sharing it on Facebook, and
that meant a lot to me. Kids I had never even talked to at school were
sharing the video."

He described the national publicity since posting the video "one of the craziest things in the whole world," but he's still waiting for an answer. When ET reached out to Miley's rep to see if she does plan to respond, the answer was that she's currently busy getting ready for her "Bangerz" tour.
